Add DiskS3NoSuchKeyErrors Metric

Why it matters

This feature introduces a new metric to track occurrences of 'No Such Key' errors when accessing data in S3 storage. It helps users monitor and diagnose issues related to missing objects in their S3-backed disks, improving observability and operational awareness.

How to use it

Users can monitor the DiskS3NoSuchKeyErrors metric via their existing ClickHouse metrics collection system, such as Prometheus integration, to detect and alert on missing S3 objects errors.
